At Diet Doctor, we often get emails from frustrated or bewildered women, usually over the age of 40, who are doing everything they can to maintain a keto diet, but are still not losing weight.

Their testing shows they are in ketosis, they are following the recipes and guides, but not only are they not losing the expected pounds, sometimes they are even gaining weight.

Alas, as women get older, keeping off those pesky extra pounds often gets harder.

That’s why we’ve created this list of 10 things women ages 40+ can work into their routine to help maintain their weight or even break a weight loss stall — while still feeling their best.

Remember, we’re aiming for progress here, not perfection. So if you can’t hit all 10 of the below takeaways at all times, or if they don’t result in dropping pounds, you are in no way a failure. After all, tip No. 10 is to be realistic.

A common problem

If this is happening to you, you are not alone. Over 40 million women in the US, 13 million in the UK, and many more millions around the world are estimated to be going through menopause, which usually occurs between ages 49 and 52.¹

Weight gain is very common during this transition.²

So along with delving into the medical literature, we also tapped the knowledge and experience of some of our low carb experts — Dr. Sarah Hallberg, Dr. Jason Fung, Dr. Eric Westman, Dr. Ted Naiman, and Atkins RN Jackie Eberstein.

These 10 tips can work for anyone in a stall, meaning they’re not just for perimenopausal women. “Menopausal women certainly can have problems with weight gain, but we see it in many others, too,” says Dr. Jason Fung.

1. Don’t eat too much fat

Once you’re fat-adapted, it’s important to avoid consuming excess fat.³

One of the great joys of low carb, keto eating is including fat at every meal after years of avoiding it.

But a keto diet is not carte blanche to gorge yourself on fat, the experts note. If you want to lose weight, you have to burn your own fat stores for energy rather than consume all the energy you need by eating fat. So if you’re struggling to lose weight, stop the bulletproof coffee and fat bombs for now.

Dr. Naiman notes that when people first start a low carb or keto diet, they’ve often previously been consuming lots of carbs and are therefore dependent on glucose as their primary energy source. Initially, he tells them to eat an unlimited amount of healthy fat until they are fully fat-adapted. “You will know you are fat-adapted because you can go a long time without eating,” he says. In addition, feeling energetic and strong while eating less than 20 grams of carbs also suggests you are fat-adapted.

Once they are primed to burn fat, however, he then advises them to scale back on fat so that they will access and burn their own fat stores.

If you are experiencing a weight-loss stall, our experts recommend you look at how much fat you’re consuming and see where you might cut back without sacrificing fullness or triggering the return of cravings and hunger. Don’t starve yourself, but be mindful of excess fat.

Dr. Hallberg notes that it is easy to over-consume fat in liquids, especially full-fat whipping cream.

“Someone will come in and say they are in a weight-loss plateau. We will look at their diet and see they are consuming six coffees, with two tablespoons of whipping cream in each one,” she says. Cutting back on the whipping cream might help them get out of a stall.⁴

We discuss this concept of excess fat consumption and determining how much you should eat in our detailed guide.

2. Get the right amount of protein

For weight loss, getting the right amount of protein is key.

What is the right amount? Our general advice is to eat between 1.2 to 2 grams of protein per kilogram of reference body weight per day. So, a woman whose reference body weight (an estimation of lean body mass) is 70 kg (154 lbs) should aim for 84 to 140 grams of protein per day.⁵

Studies show that moderate and high protein diets lead to more weight loss and reduced hunger compared to lower protein diets.⁶ That’s a potentially winning combination for kick-starting or maintaining healthy weight loss.

Some of our experts are concerned that, in general, women “shy away from large amounts of protein.” After all, according to stereotypical gender roles, who’s more likely to sit down with a big steak for dinner, and who’s more likely to order the salad? As we discussed in our podcast with Stanford researcher Lucia Aronica, Ph.D., recognizing and addressing those stereotypes can help promote healthy eating.

In addition, too little protein over the long run, especially as we age, can lead to muscle loss and frailty.⁷ That’s even more reason to make sure you maintain adequate protein intake.

3. Try intermittent fasting

After starting a low carb diet, many people naturally stop eating breakfast — they just aren’t hungry when they wake up. An important rule of low carb eating is to eat when you are hungry and stop when you are full. So if you aren’t hungry, try intermittent fasting (IF).⁸

Start by skipping breakfast and just eating lunch and dinner within an 8-hour window, which is called a 16:8 fast. Or you can try eating dinner one night, then fasting until dinner the next night, which is known as a 24-hour fast.

Dr. Fung suggests not doing the same fasting routine day after day but to “switch it up.” For instance, do a 16:8 fast one day, a 24-hour fast the next, followed by a day of regular eating.

He states this is because the body has a strong physiological drive to seek homeostasis — energy balance. “Whenever the body is exposed to a constant stimulus, it will become acclimated to it,” he says. ⁹

Hallberg suggests caution, however, around very long fasts lasting multiple days.

“If you are skipping meals because you are not hungry while eating a proper low carb, high fat diet, that is just fine,” she says.

But she is concerned about very long fasts in which people are ignoring hunger signals, as well as the potential for a dangerous physiological fluid and electrolyte imbalance called refeeding syndrome, which can arise after extended fasts lasting many days, once normal eating is resumed.¹⁰

On a low carb or keto diet, some people easily go without eating for 16 or 24 hours. Such fasts are safe and healthy, as long as you have some weight to lose. However, avoid fasting if you are underweight.

Eat when you are hungry, don’t eat when you are not, and stop when you are full.

4. Watch out for the carb creep

Once you have been following a low carb or keto lifestyle for a while, carbs may sneak back into your diet, particularly in the form of sauces, condiments, fruits, and nuts.¹¹

If your weight loss has stalled, closely examine what you are eating and cut back to less than 20 grams of net carbs again.

Nuts like cashews, almonds, and pistachios are easy to overeat and can contain enough carbs, fat, and overall calories to contribute to a weight-loss stall. A cup of pistachios, for example, has 21 grams of net carbs. Avoid carb cycling or cheat meals too, for now.

“For insulin-resistant people, if they are in ketosis but eat one high-carb meal, it may stop ketosis in some of them for up to three weeks,” said Dr. Westman.¹²

Keeping net carbs below 20 grams will maximize weight loss with more control over hunger and cravings, says Jackie Eberstein.¹³

Menopause meal plans

To help you achieve your goals, we’ve developed a meal plan specifically for women suffering from menopause symptoms. Each day you’ll enjoy high protein, keto, and low carb dishes, providing under 20 grams of net carbs per day.

5. Cut out alcohol

Many people love the fact that on a low carb or keto diet they can have a glass of dry wine from time to time. However, if you are experiencing a weight-loss plateau or gaining weight, cut out all alcohol for now until weight loss starts again.¹⁴ Even a few drinks a week might cause a stall.¹⁵

6. Avoid sweeteners

If you have been including artificial sweeteners like aspartame or sucralose in your low carb or keto diet, our experts recommend you wean yourself off them.

While there are not a whole lot of scientific studies, anecdotally we find when people get rid of artificial sweeteners, they are able to lose weight.¹⁶ “Come off them as soon as you can,” advises Dr. Westman.

7. Exercise

While you can’t exercise your way out of a bad diet, adding in aerobic exercise, resistance training, or a combination of the two may build muscle, which can help maintain or increase your metabolism.¹⁷

“The more muscle you add, the better your insulin sensitivity, so any sort of resistive strain you can add to your muscle can be great for weight loss,” says Dr. Naiman.¹⁸

Weight lifting doesn’t have to be excessive — 90 seconds per muscle group, twice a week, can do it. But he notes it has to be a heavy enough weight that after about to 10 to 15 lifts (reps) you cannot do another rep. This is called lifting to muscle failure.

“It is only if you go to absolute failure that you convince your body that you’re not strong enough. Your body won’t add muscle unless you send the message that it needs more,” Dr. Naiman says, noting that squats, push-ups and other body resistance methods can be just as effective as hand-held weights or weight machines.¹⁹

Dr. Westman never brings up exercise as a first step in weight loss. He wants patients to focus on the diet first. “But later on, if things are no longer working well and there is still significant weight to lose, I bring up the E-word, exercise. But I try to get them back to things that are fun for them. Exercise can help you get through a plateau.”

Dr. Hallberg notes that vigorous exercise can sometimes create a false plateau. “If you are exercising to the point of getting sore, you are tearing muscle — which is a good thing. That is how we build muscle, by micro-tears.”

But in order to deal with that, the body sets off a small inflammatory response, which may cause people to retain fluid. “So after a vigorous workout you might jump up a few pounds overnight. It is not a real plateau, it is a pseudo plateau,” she says.²⁰

Make sure you have rest days between days of heavy exercise, allowing the body to recover.

8. Get enough sleep

During menopause, many women find their quality of sleep sharply deteriorates, often because of hot flashes and night sweats.²¹

Drs. Fung and Hallberg recommend that women experiencing weight-loss plateaus aim to improve their sleep. Poor-quality sleep can disrupt the levels of cortisol — a stress hormone associated with increased abdominal fat — as well as other hormones that may contribute to weight gain.²²

Tips for better sleep include:

Sleep in a cool, dark room.
Wear ear plugs and an eye shade.
Limit screen time and blue light before bed (or try the glasses that block blue light).
Go to bed and get up at the same time each day.
Stop drinking coffee by noon and limit caffeine consumption in all forms.
Avoid alcohol before bed.
Get exposure to natural daylight each day.

9. Reduce stress

Examine the stresses in your life and see if you can do anything to alleviate some of them. Stress increases cortisol release, which may cause hunger and encourage your body to store abdominal fat.²³

But don’t stress about stress — that is a no-win.

“When we see people struggle and hit a plateau, or completely fall off the wagon, the number one cause is a life crisis of some sort,” says Dr. Hallberg. “We all have life crises — men and women — all our lives are managed chaos. We recommend people plan coping mechanisms to deal with stress.”

Stress can cause emotional eating, too, another cause of stalls or weight gain, Dr. Fung notes.²⁴

Try yoga, meditation and mindfulness techniques, relaxing walks or other pleasant diversions and hobbies. Dr. Hallberg recommends a week of slow and mindful eating, where you really pay attention to taste, textures, and hunger cues. Eat slowly, deliberately and mindfully.

Dr. Westman notes that even worrying about your weight can be a stressor. While tracking weight and food intake is often helpful, if it becomes too stressful, Dr. Westman suggests not monitoring these for a while and just going by how you feel.²⁵

10. Be realistic

Both Dr. Hallberg and Jackie Eberstein note that having realistic expectations is particularly important for women of all ages.

Some women are aiming for an arbitrary number on a scale, perhaps from a long time ago or an idealized weight they have never achieved — a number that has no real bearing or relationship to their actual health and wellness.

“This is one of the really big issues I see for women — it’s so much entwined with psychology, self-esteem, and societal pressure, and in many ways outside of women’s control,” says Dr. Hallberg. “They succumb to ways they think they need to be, rather than what is healthy for them. If you see victory as only a number on a scale, you are going to sabotage yourself.”

Jackie Eberstein agrees: “Measure your success by a loss of inches, rather than the scale.” She encourages accepting that weight loss in middle age will be slower than when you were younger.

“Remember that you’re in this for the long haul. It’s an investment in your health as you get older. Have patience. Your long-term goal is to make a permanent lifestyle change as well as lose the excess fat.”
